Definitions

  • the present invention relates to an interconnecting electrical connector to be provided between a pair of mating connectors or the like for interconnecting them.
  • Such an interconnecting electrical connector is disclosed in US Patent 5,395,252.
  • this connector has a contact element 51 which is made by stamping a metal sheet to provide a strip member having a pair of mounting wings 51A and is bent in the direction of sheet thickness to provide the substantially S-shaped contact element.
  • a slit 53 is provided in a housing 52 and has a pair of retention grooves 54 in opposed side walls.
  • the contact element 51 is held in the slit 53 by press-fitting the mounting wings 51A into the retention grooves 54 such that middle portions 51B are brought into spring contact with the side walls of the slit while both of the contact ends 51C project from the slit 51.
  • connection pads 61A and 62A are brought into spring contact with the contact ends 51C. In this way, the interconnecting connector is flanked by the mating connectors 61 and 62 to interconnect them.
  • the contact element of Fig. 11 has two functions; i.e., as a spring to provide contact forces with the mating connectors and a transmission path for transmitting signals. Since it is made in the form of an S-shape to provide a satisfactory spring characteristics, the transmission path becomes long. However, the increased speed of signals has made it difficult to meet the two requirements simultaneously. In transmitting high-speed signals, the shorter the contact element, the lower the self inductance of the transmission line. The short contact elements, however, provide limited movements of the contact points, failing to provide stable spring contacts.
  • the sliding movement of the contact points 51C with respect to the contact pads 61A and 62A is made by flexure of the contact points 51C about the middle points 51B.
  • the contact points 51C extend substantially upwardly from the middle points 51B so that the amount of sliding movement is small. Consequently, the contact points 51c are brought into little sliding contact with the contact pads 61A and 62a, failing to provide the so-called "wiping effects.” This leads to poor contact resulting from the accumulation of dirt and dust.
  • an object of the invention to provide an interconnecting electrical connector which is able to provide satisfactory sliding movement of the contact points, a short transmission path and a high reliability regardless of varied positions of the contact points or warping of the housing, excellent electrical characteristics and wiping effects, low manufacturing costs, and an easy assembling structure.
  • a contact element 1 is made by stamping a metal sheet and is flat and is not bent in the direction of thickness of the metal sheet.
  • the contact element 1 comprises a vertical fixing section 2, a transmission section 3 beside the fixing section, and a flexible section 4 to connect the transmission section 3 to the fixing section 2.
  • the fixing section 2 has a width sufficiently rigid to withstand the insertion force with which the contact element is inserted into a slit of an insulative housing.
  • the height of the fixing section 2 is set less than the depth of the slit.
  • the flexible section 4 is connected to the fixing section 2 by a linking portion 5 and extends upwardly to form a clamping recess 6 and laterally in a few curves so that it is readily flexible.
  • the flexible section 4 is connected to the transmission section at the other end.
  • the transmission section is made relatively rigid and has a vertical portion with a contact point 3A and a horizontal portion with a contact point 3B.
  • both of the contact points 3A and 3B are protruded from the slit to a certain extent.
  • the positions of the contact points 3A and 3B are offset laterally.
  • the insulative housing 10 has upper and lower flat surfaces 11 and a plurality of slits 12 extending between the two surfaces.
  • a mating connector or the like is to be mounted on each of the surfaces 11.
  • Each of the slits 12 is made sufficiently large to accommodate one of the contact elements 1 and has an engaging island 14 therein.
  • the contact element 1 is inserted into the slit 12 from the bottom, with the fixing section is held by an inserting tool.
  • the clamping recess 6 fits over the engaging island 14 to hold the contact element 1 such that the upper and lower contact points 3A and 3B project from the upper and lower surfaces 11.
  • a mating connector is placed on each of the surfaces 11 of the insulative housing 10 such that the contact sections of the mating connector are brought into spring contact with the contact points 3A or 3B of the contact elements 1 so that the connectors on opposite surfaces are connected through the contact elements 1.
  • the contact sections 3A and 3B receive forces from the connectors, causing a bending moment about the linking portion 5 because their work points are offset laterally.
  • the flexible section 4 is flexed about the linking portion 5 so that the contact points 3A and 3B are moved downwardly to the surfaces 11 of the housing 10. Consequently, the contact points 3A and 3B are moved not only in a vertical direction but also in a horizontal direction. As a result, the contact points 3A and 3B make sliding contact with the contact sections of the mating connectors, thus producing the wiping effects.
  • a plurality of contact elements 1 are connected to a carrier 9 at the fixing sections 2 to make simultaneous insertion into a plurality of slits by an automatic machine. After insertion, the contact elements 1 are cut off from the carrier 9 at notches 9A.
  • a portion of the fixing section 2 is bent at right angles with the fixing section 2 to provide a latch projection 2A, and a latch shoulder 12A is provided in the slit 12 of the insulative housing 10 at the position corresponding to the latch projection 2A.
  • the latch projection 2A engages the latch shoulder 12A, bringing the contact element into a predetermined insertion position.
  • the contact element 1 is bent at the linking portion 5 so that the fixing section 2 and the flexible section 4 are linked in the form of a crank as viewed from above.
  • the slit 12 is also made in the form of a crank so as to receive the crank-shaped contact element 1.
  • a plurality of slits 12 are provided such that each pair of slits 13 make a point symmetry and the receiving section 13A are parallel to each other. This makes it possible to insert identical contact elements 1 into the paired slits 13 in the reversed position so that the contact points 3A and 3B of theses contact elements are moved in opposite directions. Consequently, the plurality of contact elements offset each other in sliding contact, thus not only providing wiping effects but also minimizing poor contact resulting from a shift of the mating connector.
  • the fixing section 2 is connected to the transmission section 3 and the flexible section 4 at an angle ⁇ .
  • the portion of a slit 12 to receive the fixing section 2 also is made at the angle ⁇ .
  • Some abutment projections are provided on the fixing section 2 to abut against the walls of the slit 12 to provide a reactive gripping force.
  • An engaging shoulder is provided on the wall of the slit 12 to determine the depth of insertion of the contact element.
  • a plurality of contact elements are linked to a carrier such that the fixing sections lie in a plane (at the angle ⁇ ) for simultaneous insertion into slits by an automatic machine.
  • the transmission section 3 extends in a certain direction.
  • the contact points 3A and 3B are connected by the minimum path and produce a bending moment about the linking portion 5 when they are brought into contact with the mating connectors.
  • a line connecting the contact points 3A and 3B is inclined in opposite direction to that of Fig. 7.
  • the contact element 1 has a pair of fixing sections 2, and the slit 12 of the housing 10 has a pair of recesses for accommodating the fixing sections 2.
  • a pair of flexible sections are provided on opposite sides of the transmission section 3, maximizing the recovery force.
  • a pair of contact points 3A and 3B are provided on one side of the transmission section 3 to connect adjacent connectors 21 and 22 on a surface of the housing 10.
  • a slit 12 is provided at a corner of the housing 10, and a contact element 1 is inserted into the slit 12 from a side such that the contact points 3A and 3B project from the top of the housing lo.
  • the connection pads 21A and 22A of the adjacent connectors 21 and 22 on the upper surface of the housing 10 are connected by the transmission section 3.
  • the point of combined forces on the contact points 3A and 3B is offset from the linking portion 5 so that a bending moment is produced about the linking portion 5, thus flexing the flexible section.
  • the length of a transmission line is minimized regardless of the flexible section thereby providing a low self-inductance, excellent high-speed transmission characteristics including impedance matching, low conductive resistance, and high d.c. current capacity.
  • the setting of spring characteristics of a flexible section is not restricted by transmission characteristics so that it is possible to provide a spring having large amounts of replacement.
  • the heat generated in the transmission section is discharged from the flexible section, thus maximizing the current capacity.
  • the contact points are brought into close contact with the contact portions of a mating connector, thus maximizing the wiping effects and improving the contact reliability.
  • the rigid fixing sections are provided on contact elements so that a plurality of contact elements are pressed into the housing by holding a portion of the fixing sections, facilitating mechanical successive or simultaneous insertion of contact elements, thus maximizing the productivity
